High performance concrete potholes repair for road paving
How to Patch A Hole In your Driveway!
Step1: Joint-cutting
Step2: Chiseling
Step3: Chisel finished
Step4: Blowing
Step5: Mixing SC concrete repair material with water
Step6: Repair finished
What is the effect after repaired?
We follow observation to repaired effect after restore traffic.
Initially achieved expected effects,Results as follows:
1)1 hour restore traffic,reduce traffic pressure,effectively prevent the happening of accident.
2)High adhesion strength with original concrete.
3)High compressive flexural strength.
4)Without drying shrinkage joint in repair combining area.
5)Uniform color with original concrete
6)Expansion shrinkage coefficient is basically same.
Testing data of SC concrete repair material:
Test items | Unit | Technical requirement | Test result | Individual conclusion | |
Setting time | Initial setting | Min | ≥20 | 25 | Meet requirement |
Final setting | ≤60 | 35 | |||
Compressive strength | 4h | Mpa | ≥20 | 33.0 | Meet requirement |
1d | ≥40 | 66.1 | |||
28d | ≥50 | 90.5 | |||
Pull strength | 28d | Mpa | ≥2.0 | 2.8 | Meet requirement |
Expansion rate | 28d | / | 0.00%-0.1% | 0.01% | Meet requirement |
SC concrete repair material also repairs for:
Benefit analysis:
SC cement road repair material have super strong compressive strength,
adhesion strength and durability.Rapid,efficient repair to disease area.after completed repair,
1 h can open to traffic.
Compared with cement road paving asphalt, this method have 4 big advantage:
1)Can save some money of repairing in earlier stage.
2)Repair service life is long
3)Road bearing capacity is high
4)Adhesion force is far more than asphalt, save time and labour in later period maintenance,
don't need repair again and again.
